A. Castrol Hyspin AWS 100 is designed for severely stressed hydraulic systems requiring a high level of anti-wear performance. The ISO VG 100 viscosity is the heavy-duty grade suited to high-pressure hydraulic systems, heavily loaded circulation systems and hot-ambient operation.
A. Castrol Hyspin AWS 100 is supplied at ISO VG 100 — a heavy-duty grade in the Castrol Hyspin AWS range.
A. Castrol Hyspin AWS 100 meets ISO 6743-4 HM; DIN 51502 and 51524 HLP; and ASTM D6158.
A. Both are Castrol Hyspin AWS zinc-containing anti-wear hydraulic oils with the same classifications. AWS 46 is ISO VG 46 — the standard general-service viscosity. AWS 100 (this product) is ISO VG 100 — the heavy-duty viscosity for high-pressure or hot-ambient operation. Select per the hydraulic equipment manufacturer's required ISO VG grade.
A. Yes, the Castrol Hyspin AWS range uses a zinc-containing anti-wear additive system.
A. API and ACEA are the universal lubricant performance standards every reputable oil meets. They are your baseline check — match the code your handbook specifies (e.g., API CI-4 or ACEA E7 for heavy-duty diesel) and the oil is technically suitable for your machine. Every oil on our site lists its API and ACEA classifications.
A. An OEM Specification is the lubricant requirement set by a vehicle or equipment manufacturer (e.g., MB 228.3, VW 504.00). When an oil lists the code, the oil manufacturer has developed and tested it to meet the criteria the equipment manufacturer requires. Match the code in your handbook and you have a lubricant engineered for your machine.
A. An OEM Approval means the oil has been formally tested and signed off by the equipment manufacturer and listed on their official approved-products register (e.g., MB-Approval 228.3). An Approval confirms the oil is recognised by the equipment manufacturer for service use in their machines.
